Fuel | Injection Pump Working Principle - Animation

: To stop injection, a helical groove on the plunger eventually uncovers a spill port . This allows pressurized fuel to "spill" back into the lower-pressure gallery, causing the delivery valve to close instantly.

: When you press the accelerator, a control rack rotates the plunger. This changes the position of the helix, determining how long the spill port stays covered and, consequently, how much fuel is delivered to the cylinder. Common Pump Types in Animations

: Uses a single pumping element and a rotor to distribute fuel to all cylinders in sequence, typically found in smaller vehicles. : To stop injection, a helical groove on

: When the pressure is high enough to overcome the spring force of the delivery valve , it snaps open, sending a high-pressure pulse of fuel through the lines to the injectors.

: Features individual plunger units for each engine cylinder, common in larger diesel engines. : When you press the accelerator, a control

: As the plunger reaches the bottom of its stroke, fuel from the supply tank floods the barrel through inlet ports .
